摘要
Though uptake of beneficial foreign DNA confers fitness advantages to bacteria, the mechanisms protecting bacteria from harmful foreign DNA have been unclear. A new study suggests that the H-NS protein transcriptionally silences invading DNA by recognizing its low G-C content, thereby protecting cell viability during bacterial evolution.
